Abstract

A process for the preparation of crosslinked water-soluble polymer particles comprising combining an aqueous polymer solution comprising a water-soluble polymer, particularly a polysaccharide, and an aqueous medium, and an oil medium so as to form an emulsion of droplets of the water-soluble polymer, and adding to the emulsion a crosslinking agent capable of crosslinking the water-soluble polymer so as to form crosslinked water-soluble polymer particles, the particles formed thereby and aqueous dispersions thereof. The invention also encompasses a method comprising administering to a patient in need of treatment an aqueous suspension of the water-soluble polymer particles.
